The 3003 aluminum strip is a common product of Al Mn alloy series which is containing manganese alloy elements. 3003 series aluminum strip has excellent rust resistance, also known as rust proof aluminum strip, with good welding and corrosion resistance. Usually used for processing some parts which needs to have good formability and high corrosion resistance, such as kitchen utensils, food and chemical products processing and storage device, tank, tank transport liquid products, make-up plate, photocopier roller, ship timber plate.

As AL-Mn alloy, 3003 aluminum strip is one of the most widely used aluminium alloy, the strength of aluminum alloy strip is not high (slightly higher than that of pure aluminum), which can not be strengthened by heat treatment, often adopting cold processing methods to improve its mechanical properties. In annealing state, 3003 aluminum strip has a high plasticity, in the semi cold hardenin, the plasticity is good. When cold hardening state, the plasticity is low, with good corrosion resistance and good weldability.. The applications of 3003 aluminum strip including high plasticity and good weldability, low load parts working in a liquid or gaseous medium such as mail box, gasoline or lubricating oil duct, various liquid containers and other small parts of low load.
